A hearty meat sauce makes this spaghetti a crowd pleaser. Even though this recipe serves 100 people, it is very easy to make. This needs to simmer for 2 or 3 hours, so make it well in advance. You can even make the sauce the day before--on the day of your event, just boil the noodles and reheat the sauce. This is also great for OAMC-allow sauce to cool, divide into containers and freeze.
